The 32-year-old, who delivered her first daughter, North West, on June 15, is reportedly on a strict diet and exercising with her personal trainer daily in a bid to lose as much weight as possible before she steps out in public for the first time since giving birth, reported Contactmusic.
A source close to the 'Keeping Up with the Kardashians' star said that the brunette beauty "wouldn't stop talking about her body" in the delivery room and "she kept asking her sisters if she looked smaller and skinner after giving birth."
Despite working with celebrity trainer Tracy Anderson throughout her pregnancy, Kardashian is worried that her body will never look the same again.
